那些遇到过的问题

/ usr/bin/env ruby​​没有这样的文件或目录:使用capistrano 3,capistrano/rbenv,capistrano/bundler和capistrano/rails(使用rails 4)

pat*_*den 27 ruby capistrano ruby-on-rails

我正在使用capistrano,capistrano/rbenv,capistrano/bundler和capistrano/rails.我在capistrano编译资产的步骤中收到此错误:

# definition into the server list. The second argument
# something that quacks like a has can be used to set
# extended properties on the server.
#server 'example.com', user: 'deploy', roles: %w{web app}, my_property: :my_value

顺便说一句,我认为它与之无关$PATH,因为bundle install运行得很好.

有谁知道发生了什么？

好吧,因为我有同样的问题,我花了很长时间来解决它:

您可能想知道为什么当您使用ssh使用shell登录时,此命令无法正常工作.

我不是专家(当我错了时,请纠正我):事情是使用ssh登录远程服务器有几点不同.引用capistrano的文档:

这真的是一个关于Capistrano使用哪种shell的问题,它是关于登录,非登录,交互或非交互的可能性的矩阵.

它们在这里有一个奇特的图形(在底部),它们说明了在登录过程中执行的文件的路径.- 如果您想继续阅读本主题,给定的来源也很有趣.

出了什么问题？

当您使用ssh登录时,您(在登录时)执行多个文件(例如,当您使用bash时.bash_profile).通常,您的$ PATH变量会通过几个路径扩展到您的环境中的重要功能.但是不同的登录"样式"包括不同的文件.

正如文件中所述:

默认情况下,Capistrano始终指定一个非登录的非交互式shell.

在我的情况下,这导致我的登录文件.bash_profile不包括在内但它包括我的rvm的设置.capistrano登录会话不知道我的rvm路径的结果.

我怎样才能解决这个问题？

对我来说,它竟然只是该取消注释中的要求"Capistrano的/ RVM"(由于我使用RVM)在该行Capfile(位于轨项目的根.

希望能帮助别人.

编辑:

并确保包含gem 'capistrano-rvm'在Gemfile中!

我使用rbenv时遇到了同样的问题.为我解决的是在捆绑器之前包括rbenv库 - 而不是之后.订单结果非常重要.这是我的Capfile中的内容:
